I found an encased set of 1943 steel pennies. It has 4 pennies in it. 3 are facing front and 1 is facing back showing the wheat cent. On the front on the left is a drawing of Abe Lincoln and superimposed over it is the raising of the flag at Iwo Jima. There is also another soldier behind them with arm raised. The back is all black with a description of why steel was used as an emergency. I was wondering if this is a good find, or fairly standard?
